If you're wanting something similar to SteamOS right now that has much wider hardware support for your gaming handhelds like the Lenovo Legion Go, ASUS ROG Ally, GPD, Ayaneo or even your laptop / desktop then Bazzite is likely one of the best choices.
What is the hdmi 2.1 problem?
The licensing on HDMI doesn’t allow open source implementations of at least some of the driver stuff.
So it works on Nvidia because of the closed source driver.
(I have not dug into details obviously)
and because of this, can’t get 4k120 for my tv monitor which doesn’t have displayport :( and similar size oled monitors are very expensive.
Ah yeah ok was wondering why u wouldn’t use DP instead. Couldn’t an adapter work though?
adapter would work but i can only find one and it has bad reviews
Wouldn’t a DP - HDMI cable work?
(Don’t know anything about this)
There’s pretty much a single DP -> HDMI adapter that supports VRR by Cable Matters. Officially I don’t think VRR should work over adapters, or at least other manufacturers don’t invest the time to make it work.
